MUMH 5010: Introduction to Research in Music: Music Library Call Numbers

Introduction to Research in Music (various instructors)

Call Number Overview

Library of Congress call numbers for music items

The UNT Libraries currently use the Library of Congress system of call numbers to classify most of the materials in our collections.  Classification causes similar items to be together on the shelves.

Library of Congress call numbers use both letters of the alphabet and numbers. 

For most fields, the letters in call numbers have nothing to do with the names of the topics in question. Music is one of very few exceptions.

The two kinds of call numbers for music books start with ML and MTML stands for music literature, while MT stands for music theory or music teaching. Call numbers for musical scores start with M.

Local numbers for recordings

The call numbers assigned to the CDs in our collection are local numbers we created here. They begin with LPCD. These numbers do not classify CDs; instead, the next CD we add to our collection gets the next LPCD number. That is why browsing our CD collection would not be a good way to find specific recordings. Our local numbers for LPs start with LPZ; our LPs are all in remote storage, and can be requested for delivery to the Music Library. If you do not have a record player at home, we have one you can use in the Music Library.


Most of our print journals do not have call numbers. Instead, they are shelved in alphabetical order by journal title. There are a few exceptions, however. Annuals, or journals only published once a year, usually have call numbers. Thus, if you are searching for a journal by title on the shelf and cannot find it, look it up in the catalog. It may be one of the annuals, and you will need to look for it under its call number.
